WINTER OPERATION
CAUTION
Extreme care must be taken to assure that the machine and its associated tools are protected
from freeze damage. Freeze damage may be extremely expensive to repair and is not covered
under the warranty. If below freezing temperatures are experienced the van must either be ga-
raged in a heated area or the equipment must be properly winterized.
WINTERIZING
NOTE: Undiluted windshield washing antifreeze is sufficient for temperature down to 10 de-
grees. For protection at lower temperatures, permanent engine antifreeze must be used. Some
“RV Antifreeze” (for portable systems) may also be used for lower temperatures. Before clean-
ing operations the antifreeze must be flushed from the system.
White Magic will neither provide warranty coverage nor be held responsible for any damage
caused by freezing.
1. Drain recovery tank and close the drain valve.
2. Rotate the temperature control knob to “Winterize” and start machine in
The normal manner. Block the vacuum inlet to the recovery tank then spray a
small amount of WD40 or equivalent oil into the blower through
the vacuum relief valve located on the top side of the blower. This will prevent
rust from developing in the blower if the machine is left idle as well as lubricate
the vacuum relief mechanism.
3. Flip the Pump Power switch to the “ON” position.
4. Turn the Chemical Switch to the “ON” position.
5. Attach any tool to either wand outputs #1 or #2.
6. Remove chemical draw line from chemical jug and place it into a container of
antifreeze. Fully open the chemical adjust valve (turn counterclockwise) until a
minimum flow rate of 5+ GPH is reached when the tool is turned on.
7. Once you observe that the antifreeze is drawn through the chemical line, flow
meter and pulse pump, allow machine to continue to run another ten to fifteen
seconds then turn the chemical switch to the “OFF” position. Close the chemical
adjust valve (turn clockwise).
